Spain) were grown in a glasshouse, on sandy soil with nutrient solution and four salt treatments (O, 10, 50 and 100 mM NaCl). Plants (five replicates per treatment and age) were harvested at 50, 90 and 120 days after germinatíon. Sodium, chloride and potassium were determined for each plant in leaves, stems and roots. Total dry weight reduction with salinity was associated with increasing levels of sodium and chloride in plants and decreasing potassium uptake.
